Testing Information for Motorcycle Stators
Battery charge: 13.5 – 14.5 volts D.C.
Check Stator (1st test)
· Unplug 3 stator wires
· With engine off, check continuity between all 3
o The readings should be fairly even
· NO continuity from any 3 stator wires to engine case (Ground)
Check Stator (2nd test)
· Unplug stator from the harness
· Start engine
· Set meter to A.C. volts
· Check A.C. volts from 1 wire to the other: test all 3 combinations (A to B, B to C, C to A)
o Volts at idle: approx 15-20
o Volts at 3000-5000 RPM: approx 50-80

Wires from stator
Stator must pass both tests to be good.
If stator tests good and there is still no charge at battery (13.5-14.5 volts D.C.), suspect bad rectifier/regulator or bad wiring.
